Will cleaning extend life?
Yes — less strain on fan motor and better heat exchange.
Mini Split Cleaning vs Replacement
Most odor and airflow issues don’t require a new unit — they need a proper deep clean.
If the unit is under 10–12 years old and only has odor, dirt, or weak airflow — clean first. Replace when compressor fails, refrigerant leaks repeatedly, or repair exceeds ~50% of replacement cost.
Clean when
- Smell or mold is the main complaint
- Coil visible dirty
- Unit otherwise runs fine
Consider replace when
- Repeated refrigerant leaks
- Compressor failure
- R-22 legacy equipment (rare on mini splits)
